Introduction

These robust TRV’s are primarily designed for offshore use. The compact size and weight allows it to be economically transported and deployed. The TRV class is large enough to provide a stable platform for video and sonar surveys offshore and with most ancillary 3rd party data acquisition. The TRV excels where productivity, reliability, ultra-high thrust, and minimal down time is essential to a project’s success.

Standard Features and Benefits

Frame
The TRV Series has an open, angular frame made of T6061 marine grade aluminum which allows superior through flow for better hydrodynamics. The rugged frame is designed to take abuse and allows secure mounting of any auxiliary equipment. Finally, the aluminum frame contributes significantly to the mass required for stability.

Performance
The thruster configuration on the TRV-005 (Port, Starboard, Lateral and 2 x Verticals) allows for a 6 kt. Forward, 3 kt. Lateral and 4 kt. Aft capability. In addition, the TRV-005 rotates 120 degrees per second and provides the above performance figures at only 45% power. This is designed into the TRV-005 whereby the desired performance is achieved without running the system at close to maximum power, thus providing greater reliability on all components.
– The TRV-M performance allows 4 kt fwd, 3kt aft and 2kt lateral and is more than capable of operating in most conditions.
– TRV-HD being the largest vehicle currently operated by SSI allows a comfortable 3kt fwd, 2kt aft and 1.5 lateral performance.

Modular Design
In an attempt to minimize downtime, the TRV systems have a totally modular design. This allows minimum expertise to maintain the TRV systems, keeping the vehicles in a fully operational condition. Where the TRV Systems differ from all other ROV’s is that should a fault occur, the suspect TRV module is simply exchanged with the relevant Spare module returning the TRV into 100% operational condition without opening any housings and minimizing de-bugging efforts. The suspect Module is then returned to SSI for repair / testing. From convenient, easy to remove connectors, oil filled cables and simplicity in removing the foam block for complete access, the TRV systems are designed for the true offshore environment.

ManeuverabilityTRV-005 and TRV-M have the ultimate in vehicle maneuverability with ability to proceed Fore, Aft, Rotate, Lateral, Vertical (normal mode), Vertical (pitch mode). The TRV-HD performs as a workhorse should, very stable in all 3 axis of movement.

Penetrators
All TRV’s come standard with 3 spare penetrators to allow for additional functions as they become necessary.

LED Lighting
All TRV’s come standard with Five LED lights on 2 circuits with 0 – 100% variable gain.

TetherTRV’s allow up to 3300’ excursions in live boat mode. Deeper options are available with side entry cage. TRV’s comes standard with a spare 1500’ terminated tether. Other tether lengths are available as per client’s request.
